Germanium to which 1024 m–3 as atoms have been added is an extrinsic semiconductor at room temperature, and virtually all the as atoms may be thought of as being ionized (i. e., one charge carrier exists for each as atom).
(a) is this material n-type or p-type?
(b) calculate the electrical conductivity of this material, assuming electron and hole mobilities of 0.1 and 0.05 m2/v-s, respectively.
